Experimental Investigation of Carbide Tool Wear on Milling Ti6Al4V with Water Vapor Cooling and Lubricating

The machinability of Titanium Alloy Ti6Al4V is poor, the traditional methods to machining is application of cutting fluids with the active additives which cause environmental pollution and health problems. In this paper, the water vapor was applied on milling instead of cutting fluid for the aim of green milling Ti6Al4V. The effects of water vapor, oil emulsion and dry cutting on tool wear have been examined in milling of titanium alloy Ti6Al4V with carbide tools YG6, the wear morphology of rake and flank tool face was studied. The results of experiments indicated that application of water vapor reduced the tool wear and increased the tool life.
